Open-Collector arbeiten kann? Ich schlage nun vor, einen Bustyp zu wählen, der von den kleineren AVRs (z.B. AT90S2313) hardwaremäßig unterstüzt wird. Das wäre eine RS232-ähnliche Konstruktion: MASTER out ---->----/----------------------------/--------- in ----<----|--/-------------------------|--/
für den ATMega161 zu haben (hab ich noch 2 Stück von :-). In dessen Sockel könnte man z.B. auch den AT90S8515 einstecken, falls nicht so viel Speicher gebraucht wird. Wichtig bei dieser Wahl ist nur, dass der verwendete Master-Mikrocontroller mindestens 2 RS232-Schnittstellen hat. Eine für die Slave-Anbindung

. Inductive Series resonant freq Frequency Parallell resonant freq Capacitive Crystals below 30MHz can be operated at any frequency between the series and parallel resonant frequencies, which means that they are inductive in operation. High- frequency crystals above 30MHz are usually operated at the series resonant frequency or overtone frequencies, which occur at multiples of the fundamental frequency. Adding a capacitive load, C ,Lto the crystal will cause a shift in frequency given by Equation 2-3. The crystal frequency can be tuned by varying the load capacitance
by a fixed-frequency, pulse-width-modulated (PWM) regulator. In general, each converter operates at continuous conduction mode (CCM). At light loads, the negative converter can enter discontinuous conduction mode (DCM). As the load current decreases, the converters can enter a power-save mode if enabled. This works independently at both converters. Output voltages can go up to 15 V at the boost output and down to –15 V at the inverter output. 20 TPS65130,TPS65131 www.ti.com SLVS493B–MARCH 2004–REVISED SEPTEMBER 2004 DETAILED DESCRIPTION

the forward converter works at the pre-regulated intermediate circuit voltage. This means that a higher transformer ratio can be selected, reducing the current load for the MOSFET. Furthermore, a larger duty cycle can be set during
